DYEINGr-MACHINE.

Specification of Letters Patent.

Patented Mar. 2, i920.

Application led October 26, 1917. Serial No. 198,567.

To all w/Lom t may concern:

Be it kno-wn that I, HOWARD M. DUDLEY, a citizen of the United States,residing in the city of Philadelphia, county of Philadelphia, and Stateof Pennsylvania, have invented certain new and useful improvements inDyeing-Machines, of which the following is a full., clear, and exactspecifi-l cation.

My invention relates 4to dyeing machines and refers particularly tomachines suitable for the dyeing ofteXtile fibers, and like materials,by means of a circulating liquid.

One object of my invention is a device whereby textile fibers may bedyed evenly and uniformly while in a compressed condition.

Another object of my invention is a device whereby a liquid may bepassed uniformly and thoroughly through a compressed mass of fiber.

Another object of my invention is a device whereby the formation ofchannels may be prevented while passing| a liquid through a compressedmass of fiber.

Another object of my invention is a device whereby the condition of thetreated liber may be determined without interrupting the process oftreatment.

Another object of my invention is a device compressing ai testing devicewhereby the condition of the treated fiber may be accurately determinedwithout opening the dyeing chamber.

These and other objects of the device of my invention will be evidentupon a consideration of my specification, drawings and claim.

Great difficulty is experienced in obtaining even and uniform dyeings oftextile fibers in those machines in which the fiber is treated whileunder pressure to the action of a dyeing liquid. Under these conditionsthe liquid has a tendency to form channels or passages through thefiber,through which more liquid passes than through other portions ofthe liber, thus causing uneven results.

It is evident that when liber is compressed between two plates havingopenings with parallel sides, the liquid forced through-the openingswill be impinged in a ser1es of liquid columns against the fiber forcingitself therethrough in a series of channels,

the intermediate portions of the mass being less affected bythe liquid.

It further evident that unless the liquid pressure is absolutely equalupon all parts of the foraminous plates, more liquid will be forcedthrough some of the holes than through others causing uneven dyeings.

AIt is further evident that au equal liquid pressure must be maintainedat all times throughout the entiremass. I

.My device accomplishes all of these three vital elements of successfuldyeing and pre sents a method whereby all portions of the fiber will Vbetreated equally by the impinged liquid whereby the formation of channelsis prevented, whereby the liquid pressure will be absolutely equalizedover the entire foraminous plate and whereby a uniform, liquid pressurewill be maintained throughout the iiber mass.

In order to equalize the liquid pressure over the entire foraminousplate, I pass the liquid int-o the device through a series of conduitsdistributed below a foraminous plate, thus distributing the liquid asevenly as possible, from these the liquid passes through a foraminousplate, thus breaking up any currents that have been formed, into achamber from which it passes through a second foraminous plate into thefiber mass. This chamber between the two foraminous plates causes acomplete equalization of the f liquid pressure and allows an absolutelyuniform and equal amount of liquid to pass through all portions of thefiber mass.

In order to prevent the formation of channels through the mass due tothe impinging of Vliquid columns upon the liber, the foraminous plate ofmy device upon which the liber rests consists of a series of inwardlyprojecting members, thus presenting a maximum of liber surface to theac:- tion of the liquid and causing it to penetrate the entire mass inan equal and complete manner.

In order to maintain a uniform liquid pressure throughout', the entireliber mass, the two foraminous plates of my device, between which thefiber is compressed, are eX- actly similar in constructie-11, the exitof thc liquid from the mass therefore being under the same conditions asits entrance into the mass.

`-By means of my testing device, the condition of the dyed ber may bedetermined a-t any time without opening' the dyeing chamber orinterrupting the operation, the value of which device is evident.

l also provide means whereby the liquid may be passed in oppositedirections through the fiber when desired.

Having thus broadly described my invention: l give the following exampleof one form of my device. i

y The device of my invention, as illustrated, comprises a receptaclehaving the side wall 20, within which is the foraminous plate 21,resting upon the annular otlset'22 of the side wall 20. Spaced above theplate 21, and supported therefrom by the annular member 23, is aforaminous plate 24. The bottom 25 of the receptacle contains a seriesof converging tubes 26, 26, 26, the interior ends of lthe tubes 27, 27,27 being extended upwardly. rThe outward ends of the tubes 26, 26, 26terminate in a chamber 28 within the extended portion 29 of thereceptacle. Removable from and slidable within the receptacle is aforaminous plate 30. Aremovable top 31 contains a series of convergingtubes 32, 32, 32 similar to those in the bottom 25, the interior ends ofthe tubes 33,

33, 33 being extended downwardly. The outward ends of the tubes 32, 32,32 terminate in a chamber 34 within the extended portion 35 of the top.The top 311also carries the oraminous plate 36, and the y downwardlyextended portion 37 of the top is capable of abutment upon the plate 30.Screw bolts 38, 38 passing through openings in the ang'e 39 of the top31 and threaded in the holes in the flange 40 of the wall 20 allow ofthe top `being forced downwardly into the receptacle. Bolt eyes 41, 41are inserted into the top 31 as a means for raising the top.

A testing tube, shown in cross-section in Fig.7 is similarV andproportionate to the larger'devce and comprises the wall 42 and theforaminous plates 43, 44, 45 and 46 similar to the plates 36, 30, 24 and21 respectively. The threaded hollow members .47 and 48, threaded withthe interior of the wall 42 enable the compression of the fiber v101.The lower portion of the wall 42 is connected with the pipe 49 by meansof the bushing 50. The pipe 49 carries the valve '51 and is connectedwith the chamber 52 by means of the conduit 53. rlhe upper portion ofthe wall 42 is connected with the .pipe 54 by means of the bushing 55.lThe pipe 54 carries the valve 56 and is connected to the chamber 93 bythe conduit 58. By means of the bushings 50 and 55, the testing devicecan be removed from connection with the pipes 49 and 54 to allow ofcharging the same or oit examining the contents.

Plates 24 and 30, as shown in Figs. 4 and 5, consist of a series ofserrated rings 60, 60, supported by the members 61, 61.

Plates 21 and 36, as shown in Fig. 6consist of a plate 'having circularopenings 63, 63 therein. ,l

The extended top member 35 is connected to the pipe 64 which in turn isconnected to the pipe 65 by means ot' the flange coupling lThe extendedbottom member 29 is con. Ynected to the pipe 69, which carries the'valve70, and is connected vto the discharge chamber of the pump 68. Y

The pipe 71 connecting the members 35 and 29 carries the valves 72 and73 and is connectedr with the pipe 74 emptying into the top of thereserve tank 75.

The bottom of thereserve tank 75 is connected to the pipe 76, carryingthe valve 77 and connected to the receiving chamber of the pump 68. Apipe 78 carrying the valve 79 connects a dissolving tank, not shown,with the receiving chamber of the .pump 68. A pipe 80, carrying thevalve 81, enters the chamber 28. p i

In the modification ot the top member 31 and the bottom member 25, asshown in Figs. 8 and 9, the tubes 26, 26 andV 32, 32 are replaced by thetroughs or `conduits 82, 82, open at the portion toward the interior ofthe receptacle. p

rlhe modification of the plates 24 and 30, shown in Figs. 10 and 11,comprises a series lll of parallel and intercepting bars 84, 84k havingextended points or members 85, 85.

In the modification of the plates 21 and 36, shown in Figs. 12 and 13,the holes 86, 86 are square instead of round.

The operation of the device is as follows The liber mass 100 is placedwithin the receptacle and upon the plate 24. Plate 30 is then placedupon the liber mass, and the top 31 lowered into place. The pipe 61 isconnected to the pipe 65 by means of the coupling 66, and the member 35connected to the pipe 71 by means oi the nipple 91. rlhe screw bolts 38,38 are then inserted and screwed down, the member 37 pressing the plate30 inwardly until the desired pressure is obtained upon the fiber mass,the pipe 65 sliding into the-bushing 96, and the nipple 91 being turnedto take care of the downward movement of the top. The testing device ischarged with the fiber mass 101, and placed in position. All of thevalves are closed with the exception of valves 79, 70, 51, 56 and 72,and the pump 68 started.- rlhe liquid thus passes from the dissolvingtank, not shown, through the pipe 78, the pump 68, the pipe 69, thepipes 26, 26, the chamber 52, the plate 21, the chamber 92, the plate.24, the ber chamber and the ber 100 therein, the plate 30, the chamber57, the plate 36, the chamber 93, the tubes 32, 32, the pipes 71 and 74into the reserve tank 75. When sufficient liquid has been introducedinto the reserve tank, the valve 79 is closed and valve 77 opened,- theliquid then having a continuous circulation in the direction mentionedabove. At the same time the liquid passes upwardly through the testingdevice and the fiber 101 therein.

When it is desired to reverse the flow of the liquid, valves 70 and 72are closed and valves 67 and 7 3 are opened, thus allowing the liquid topass in a reverse direction through the device. From time to time, asdesired, the condition of the fiber in the testing device may bedetermined by closing valves 51 and 56 and removing the device aspreviously described. The liquid may be drained oil through the pipe 80,and water may be introduced for washing the fiber by means of the pipe94C carrying the valve 95.

I do not limit myseltl to the particular size, shape, number orarrangement oi parts as described and shown, all of which may be variedwithout going beyond the scope of my invention as described and claimed.

What I claim is In a dyeing machine, in combination, a receptacle havingimperforate sides, two foraminous plates within and extending across thereceptacle, a iber chamber between the two plates and the sides of thereceptacle, means for increasing and decreasing the size of the fiberchamber, two oraminous plates spaced outwardly from the irst two plates,a reserve tank, a conduit connecting the upper portion o' the receptaclewith the reserve tank, a pump, a conduit connecting the reserve tankwith the pump, curved tubular members above and below the foraminousplates so arranged that a liquid may be continuously forced through thetubular members, the plates, the ber chamber and the reserve tank ineither direction.
